# BifrostTransform
|
||
|
||
**Özet:** Anthropic Messages API formatı ile OpenAI Chat Completions formatı arasında çift yönlü dönüşüm yapan katman (`internal/transform/anthropic_bifrost.go:74`). "Bifrost" (İskandinav mitolojisindeki köprü) adı, two-way dönüşümü simgeler.
|
||
|
||
**Kütüphaneler:** Go `encoding/json`, `strings`
|
||
|
||
**Bağlantılar:** [[AnthropicHandler]], [[Index]]
|
||
|
||
## Struct'lar

|
||
### Anthropic → OpenAI (`AnthropicToBifrost()`)
|
||
|
||
```
|
||
Anthropic Request OpenAI Request

───────────────── ─────────────
|
||
model: "claude-3-5-sonnet" → model: "Anthropic/claude-3-5-sonnet"
|
||
system: "Be helpful" → messages: [{role:"system", ...}, ...]
|
||
messages: [{role, content}] → messages: [{role, content}]
|
||
max_tokens: 1024 → max_tokens: 1024
|
||
stream: true → stream: true
